"You can identify your health status by brushing your face", "a computer the size of a business card", "typing and chatting by eye control input method"... With the arrival of the 2022 World Internet Conference Wuzhen Summit, a new batch of "black technologies" will be presented at the "Internet Light" Expo to see what they are all about. (A computer the size of a business card.) A computer the size of a business card is in the exhibition hall. A small device the size of a business card, called Raspberry Pie, is the smallest computer in the world. This equipment, which costs only a few hundred yuan, is configured with a 4-core CPU and 8G memory. The distributed database OceanBase 4.0 developed by Ant Group can already run on a single machine. According to the field staff, despite its small size, it can not only achieve large-scale data processing capacity, but also match the performance of traditional stand-alone databases. (The "eye movement input" scheme relies on eye control input method to type and chat.) The "eye movement input" solution was demonstrated by the "eye movement input" method of Tencent Sogou Input Method. Its technical principle is that, with the help of an eye controller with built-in eye tracking technology, disabled users such as the group of people with chronic frostbite can operate the computer to complete input through eye movement and gaze. It also supports several modes such as full spelling and simple spelling input. The field staff demonstrated using eyeballs to create a "hello" on the spot. (Brush your face to test your health status.) Brush your face to identify your health status. Do you believe that brushing your face can identify your health status? An artificial intelligence health detection terminal named "Magic Mirror" displayed at the exhibition is said to be able to do so. It is reported that the terminal is a non-contact health measurement solution. It does not need any wearable and contact equipment. It uses the blood optical imaging (TOI) technology. It can accurately measure a series of important human health indicators such as heart rate, blood pressure, psychological pressure, heart load, moderate wind and heart disease risk through a 30 second facial video. (Applets test whether users are potentially suffering from Alzheimer's disease.) Applets test "lost memory", "Alzheimer's disease takes away more than memory. Families spend eight or nine hours every day to take care of and accompany the elderly"... Small programs in the exhibition hall are constantly tested. It is reported that this small program was developed by Alibaba Dharma Institute, which uses multimodal AI technology to test whether users are potentially suffering from Alzheimer's disease, so as to achieve the goal of early screening and early intervention. (Display of smart helmets.) With the popularity of takeout, smart helmets and express delivery brother are becoming a pain point in the industry. Is it OK to show a smart helmet this time. The helmet integrates a variety of modules, which can be connected with the mobile phone order receiving APP, and convert the system prompt information into voice broadcast. The smart helmet changes into a "voice assistant" every second. The takeout boy can use voice to receive orders, confirm arrival, report exceptions, navigate to the order location, and call the user's phone
